Ernest Hemingway's novel "The Old Man and The Sea" tells the story of how an aged fisherman had to struggle with a large marlin out in the sea. If he did not go fishing, he would be left starving but when he got the fish, he wasn't that strong anymore to handle the caught fish like he used to.
The old man had been in the sea for the whole night when in the early hours of the morning, his line caught some fish which he wasn't sure of yet. But he was sure it was a big fish for he couldn't easily reel it in. And with his old age and poor preparation, he had no choice but to leave the fish to tire itself out or even <em>"jump so that he'll fill the sacks along his backbone with air and then he cannot go deep to die"</em>. This whole passage shows just how unprepared he was to be handling a fish of that size.
